Description

Used for flow measurements in the lab, process flows in pilot plants, metering carrier gases in chromato graphy, indicating and controlling gases in manufacturing processes and for indicating flow rates in pumping or flow systems. Formed from heavy-walled, shock-resistant borosilicate glass, these flowmeters can be used at operating pressures up to 200 p.s.i.g. and maximum temperatures of 121ºC (250ºF). They feature fused ceramic scales that are accurate to within ±2% of full scale. Repeatability is 0.25%. Uniformly tapered bores have internal rib guides to stabilize the glass, stainless steel or carboloy floats. Flow measurement is taken by reading the center of the float on the universal scale. The number on the scale corresponds to a flow rate for the given fluid or gas on a calibration chart that is supplied. Flowmeters are available in four styles. 65mm scale, sizes 1-6 and 150mm scale sizes 1-5.

Millimeter scales indicate the height to which the float rises within the flowmeter and are correlated with specific flow rates through the use of appropriate calibration data sheets or curves. Scales of this type permit utilization of a given flowmeter for a great number of different fluids at diverse pressure and temperature conditions.

Flowmeters are housed in a black anodized aluminum frame that features an exclusive tube-lock to prevent turning during locking. Once in place, the meter will not shift under pressure or vacuum. A special magnifying window runs the entire length of the scale for easy reading of flow measurements. Tubing connectors are rear mounted for attachment to an instrument when used as a bench stand. A Leveling Base (optional) assures that the meter is vertical, eliminating error caused by friction between the float and tube.
